Treble were an all-girl trio formed in 1995 by sisters Niña and Djem van Dijk and Caroline Hoffman. They began their career by performing street concerts accompanied by acoustic guitar and djembe.
They were selected to represent their home country at the 2006 Contest in Athens but failed to qualify for the final. Post-Contest their career failed to take off as they released two singles, the latter of which was postponed until early 2007.
The girls went their separate ways in March 2010 to pursue solo careers. In 2012, Niña van Dijk auditioned for the third season of "The Voice of Holland" but was eliminated during the first live show round.
